Did i make a mistake picking up an H70 for my i7 920?

post #1 of 12
Thread Starter 
I was not pleased with the temps of the stock cooler, during prime95 and i knew that when i started turning up the clock, it would run even hotter.

I knew the h70 was essentially a no hassle way to liquid cooling, picked it up and got everything mounted. Rad is located in the 5 1/4 drive bay, with room for my single dvdrw... i haven't reinstalled that yet because i want to monitor how hot the radiator gets.

I have already noticed a substantial decrease in temps, during a 10hr run of prime95 in blended mode. 13C less on the high end, at the end of the run.

Now that i've had time to recover from my impulse buying high, i notice that i could have gotten a bit better cooling for a little more or around the same price.

Is the general idea that he H70 isnt really up to snuff? I'd like to hit 4ghz on this 920...

The H70 is nice for silent cooling, but any premade watercooling kit isn't going to keep up with a high end air cooler, try mounting it in a place you can get some fresh air, and putting some different fans on it, you should see a decrease further in temps.

The h70 is good for people with tight space requirements who cannot fit a comparable high end air cooler. It is not as cost effective but it is much less hassle than a full water loop. Those are really the only reasons to choose it over high end air or water.

For me it was good because it cleared my ram and I am not planning to do a huge overclock so it keeps my temps well within the comfort zone.

Consider getting better fans for the rad it makes a big difference.

An H70 should get you to 4Ghz with out a problem. Now that you have it I would keep it, there are better air coolers but only by a few degrees C.

Better air flow will help but it takes a triple rad setup to keep temps in the green if you plan to overclock. Can you send it back and get a better setup? Of course it will cost more but that's really your only option if you want to overclock that CPU ~4Ghz.

The only 2 coolers that perform better are NH-D14 and Silver Arrow (both air), and this is excluding any custom watercooling

H70 definitely performs well for the space it takes, and should get you to 4GHz no problem, maybe even 4.2 if your chip is good.

I didn't buy it because I didn't like the price tag, and I have space for the NH-D14

I have the radiator mounted in the 5 1/4 drive bays. There is room for me to fit my dvdrw, above the radiator. This case is probably... 8 years old? Maybe more... right now, i just want to be able to focus on the technical aspects... then work on the form.

As it stands, i do not think i can get any "fresher" air, than where it is pulling from right now. I am pleased with the 58 degree 100% load temps, after 9+ hrs.

Eventually, i will have a custom loop... i am not ready to work toward that, right now. When i do, i will move this setup to my girlfriend's pc. We just got her working with a Sandy Bridge i3, so there is much room for improvement there.

main goal is to have a 24/7 stable 4ghz, with the lowest temps possible. This will give me some room to cut my teeth and get back into the game. Last time i was overclocking anything, we had to solder the actual board to see significant gains.

your get 4ghz on a h70 no issue.. with air cooling you notice a big increase in temps with overclocking but with liquid it seems to not change a great deal..

I was getting 4 ghz on an i5 with two fans on a H50. Temps were in the mid 70's under stress testing. Like the others have said you should be able to get there/close with a H70. What kind of voltage does your i7 take to hit 4?

Do you have a pic of your rig? Most people don't have their rads mounted in the drive bay. I wonder if you are getting adequate air flow? I had my rad mounted external on top of the case. (This is a Coolgate 240MM Rad but you get the idea...)

The only reason i have the fan/rad sitting in the drive bay is because the tubes are so short on the h70, i had to make sure i could place it somewhere inside of the case. I have seen several instructions on modifying the h70 with longer tubes, more/better fluid, etc... it seems like i should have just gone with a custom loop, if i'm going to do that :shrug:

this is my first time playing with water, so i dont expect it to be perfect. I am just expecting to get some experience with it, before i put serious money into a real setup.

I can definitely tell that the flow to the rad, is not good... the fluid tubes on the h70 are not long enough to place it flush with the front of the case. I believe i can fabricate a shroud that will help guide the air i want, to the intake.

i dont even know if that will work... i have done it on some cars to help with CFM so uhh... yeah, lol.

On a side note i was able to get a stable 3.78ghz at 1.25v and bumped the qpi up 1 notch. The one thing i noticed, with my board, is that it does not have the same voltage increments as the guides say to set them at. It is typically very close, but not exact. Is this typical, depending on the BIOS running?

I have a gigabyte x58-usb3 that i used to replace my ex58-ud3r.

I am very close to 4ghz but even at 3.78, i am seeing temps of 80C after ~1hr of Prime95 and the heatsoak just gets worse as the rad isn't dissipating fast enough, so the temps just continue to climb, as time goes on.

That is my theory anyways...

Memory is patriot G series tri channel 1600... i cant remember what it runs at, but its well under 1600 with a BCLK of 180
